← ScienceWhich consequence results when dissolved iron (II) acts as catalyzing agent in hydrogen peroxide rocket propellant?
A)A decrease in combustion temperature
B)Uncontrolled, rapid decomposition of propellant✓
C)Increased propellant viscosity
D)Improved combustion stability
💡 Explanation
When iron (II) is present, it catalyzes the decomposition process through the Fenton's reaction, resulting in self-accelerating decomposition. Thus, a fast runaway oxidation reaction occurs because iron alters the activation energy, rather than producing a stable or lower-temperature combustion.
